Private Endpoints

  • Artikkeli

Azure Private Endpoint is a network interface that connects you privately and securely to a service powered by Azure Private Link. Now, Custom question answering provides you support to create private endpoints to the Azure Search Service.

Private endpoints are provided by Azure Private Link, as a separate service. For more information about costs, see the pricing page.

Prerequisites

  • If you don't have an Azure subscription, create a free account before you begin.
  • A Text Analytics resource (with Custom question answering feature) created in the Azure portal. Remember your Microsoft Entra ID, Subscription, Text Analytics resource name you selected when you created the resource.

Steps to enable private endpoint

  1. Assign Contributer role to Text Analytics service in the Azure Search Service instance. This operation requires Owner access to the subscription. Go to Identity tab in the service resource to get the identity.

Support details

  • We don't support changes to Azure AI Search service once you enable private access to your Text Analytics service. If you change the Azure AI Search service via 'Features' tab after you have enabled private access, the Text Analytics service will become unusable.
  • After establishing Private Endpoint Connection, if you switch Azure AI Search Service Networking to 'Public', you won't be able to use the Text Analytics service. Azure Search Service Networking needs to be 'Private' for the Private Endpoint Connection to work
